Ae82 pump in your ae86 tank works well. Vl lift pump and external pump also works. If you have loads of cash buy a jdm tank for what I consider stupid money.
Wiring the tank is easy for an internally mounted pump. Bulkhead wiring connectors so the ffuel doesn't run run through the insulation.
Sure the tank doesn't have regular efi baffles but you'll rarely get surge.
